add 'simple_translation.middleware.MultilingualGenericsMiddleware'
and 'cms.middleware.multilingual.MultilingualURLMiddleware'
to MIDDLEWARE_CLASSES

if you DONT want multilanguage posts you need to add 'django.middleware.locale.LocaleMiddleWare' to MIDDLEWARE_CLASSES

run 'python manage.py syncdb'

Create a page in cms and in the 'Advanced settings' section of the admin for that page for 'Application' select 'Blog Apphook'
Do this for each language you want to show posts in.
